Meterpreter Script for Prefetch-Tool (updated)

The prefetch tool has been updated. Spend the Sunday making the changes. I hope you guys like it.

Changes include:
1. prefetch.exe executable has been reduced from 3.8mb to 2.2mb. Any size smaller than this, I will have to rewrite the code in c++.
2. Prefetch tool is much faster now due to some logic issues in the previous script.
3. Meterpreter script updated to download new prefetch.exe from my googlecode project’s site on demand when new updates are available.
